What is CVE-2026-23395?

A vulnerability in the Linux kernel's Bluetooth subsystem allows the acceptance of multiple connection requests without properly validating the command identifiers. This oversight can lead to an excessive allocation of resources, resulting in a buffer overflow condition. According to the Bluetooth specification, each request must utilize a unique identifier within a signaling channel. The vulnerability arises due to the failure to check for existing channels with the same identifier, potentially leading to system instability and unexpected behavior. The issue has been addressed to enforce proper validation of request identifiers.
